This research determining benzoic acid and sorbic acid in food by high performance liquid chromatography method with C8 photodiode array detector. The detector wavelength was set at 229 nm.Mobile phase using was 1% NaH2PO4 pH 4.4 and methanol (60:40) at flow rate 1.0 ml/min. The food ten samples for quantitative of benzoic acid and sorbic acid were found in the range of 2.32-4912.2and not found - 523.06 mg/kg. Recovery percentage for benzoic acid and sorbic acid were in the range of 82-84and 80-110.Samples were analyzed have been six samples formed to the legal prescriptions
